Sierra 10.12.6 and FMP v11

I have a client whos's notebook crashed and hasily went out and bought a new one while the old one is being repaired. He can't install FMP v.11 on the new laptop which he needs to access his company's hosted application.

Has anyone experienced the same or had success installing FMP 11 on a Sierra 10.12.6 mac?

I am in Cozumel Mexico at the moment with limited internet and bandwidth and can not service this client as i nomally would, hense the reach out.

searching the Community, I found Message d'erreur au lancement de FMPA 11 (the thread is in French). Look a the last post and ask Google to translate. The user installed FMP 11 on a different computer and copied the installation to the computer where he wishes to use FMP 11. But since FMP 11 is not certified on 10.12.6, it may be buggy.

Unfortunately as new versions of macOS are released, they are less tolerant to older software.

Things get flakey with FM11 on current OS X; the Apple EULA since 10.4 has allowed for the creation of an OS X virtual machine, as long as that VM is on Apple hardware. You can install say, VirtualBox, and put up an version of OS X in that VM that is compatible with FM11.

Alternatively, if he can remote desktop into the FM11 machine and run it there, that is an option, although your statement about limited bandwidth makes for some performance concerns.
